MedChem Imaging, Inc. (MCI) is a contract research organization that specializes in the chemistry of non-radioactive and radioactive compounds for molecular imaging. Our team helps design radiotracers which provide information about target abundance, occupancy, dose response, as well as the time course of tumor uptake or brain penetration. MCI can also provide molecules radiolabeled with ³H, ¹¹C, ¹⁸F, radioiodines or radiometals.
